The aluminum nitride (AlN) ceramic has high thermal conductivity(5-10 times as the alumina ceramic), low dielectric constant and dissipation factor, good insulation and excellent mechanical properties, non-toxic, high thermal resistance, chemical resistance ,and the linear expansion coefficient is similar with Si,which is widely used in communication components, high power led, power electronic devices and other fields.Special spec products can be produced upon requests. Product Features 1.Uniform microstructure 2.High thermal conductivity* (70-180 Wm-1K-1), tailored via processing conditions and additives 3.High electrical resistivity 4.Thermal expansion coefficient close to that of Silicon 5.Resistance to corrosion and erosion 6.Excellent thermal shock resistance 7.Chemically stable up to 980°C in H2 and CO2 atmospheres, and in air up to 1380°C (surface oxidation occurs around 780°C; the surface layer protects the bulk up to bulk up to 1380°C).

Aluminum nitride ceramic thermal insulator pads are ceramic materials with outstanding properties such as high thermal conductivity and high electrical resistance. In addition, it is featured advantages such as high hardness, corrosion resistance, low dielectric constant and dielectric loss, and low CTE. Aluminum nitride ceramics have excellent thermal conductivity (7-10 times that of alumina ceramics), as the thermal expansion coefficient of silicon is similar, as a new generation of ceramic materials, more and more people pay attention to it.
